Can I get the same workout using a pull up bar as I would with a captains chair? They are cheaper, and if I can derive the same results, I don't see the need to spend a lot of money.

Using the captain's chair, you can perform a variety of exercises to help you strengthen those abdominal muscles. These exercises include the basic leg raise exercise, captain chair's kicks, and straight leg lifts. For information on how to perform these exercises, go to this website: http://www.livestrong.com/article/89646-captains-chair-exercises/.

There are few ways to increase resistance to captain's chair exercise. You can either strap weights on your ankles or place a ******** between your shins.

The least effective abdominal machine has to be the ab rocker. It is really a waste of time if you ask me. Sure, it is comfortable for the head and shoulders, but it just doesn't deliver the same results as doing crunches or using equipment like the captain's chair.

A captain's chair is one of the most effective abdominal equipment. It is an upright piece of equipment with two arm sets on the sides. Using the captain's chair, you work out both the central and lower ab muscles.

In order to add resistance when using a captains chair you will need to get creative. You can strap weights to your ankles or place a medicine ball between your shins while you exercise.

The captains chair looks like an oversized chair without a seat. It has a padded backrest, padded supports for your arms and supports for your feet. Here is a picture -

Most people use a pull-up bar for their arms; however it can also be used to work on your abdominal muscles. If you hang your legs over the bar you can raise your body up from a hanging position (quite similar to using a captain's chair).

Great to here.

First of all rule out if the adapter is burnt or spoiled. You can do this using a multimeter, the readings will give you the result. If you find fault in the adapter then you have to take the adapter to a electronics store and ask the salesman to give you a similar adapter with same polarity, power ratings and connector. This would workout cheaper and faster. The adapter will work fine.

Plz. don't forget to rate my suggestion.
